Airtac BSED Clamping Double Acting Cylinder BSED100X450S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X450S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 5500 N in either direction if air is lost. Ø100mm bore, 450mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X450S
The AirTAC BSED100X450S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force in both directions—about 3681 N each way at 0.5 MPa. The fail-safe collet lock provides a 5500 N static holding force with no live air required.
This 100 mm bore unit runs at 30-800 mm/s with a PT1/2 cylinder port and a separate G1/8 lock-release port. The -S magnet supports CMSE reed and DMSE electronic sensors. It is not a dynamic brake; engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced (allow at least 0.5 s).
Double Rod + 5500 N Rod Lock (Ø100mm)
A rod exits both ends for symmetric force and back-rod tooling, and a spring clamps the collet so the Airtac BSED Clamping Double Acting Cylinder BSED100X450S holds its position in both directions on air loss or E-stop. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage only after the rod has stopped (not a dynamic brake), and release only when both piston sides are pressure-balanced; allow ≥0.5 s for full release.

Specifications follow the official AirTAC BSED datasheet. Rod thread M20×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X450S Is Used
Vertical Lift Stops
Holds 5500 N vertical loads instantly on air loss while the double-rod delivers 5153 N lifting and lowering force.
Machining Clamps
Secures heavy workpieces mid-cycle; the rear rod allows tooling or flag mounting without losing holding power.
Pallet Indexing
Moves payloads both ways with equal 3681 N force at 0.5 MPa, locking the 450 mm stroke securely during station stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X450S the Right Cylinder?
Select this model when your application requires symmetric both-way drive force and failsafe holding during air loss or E-stop. Verify your load is under the 5500 N static holding force. If you need less force, the 80 mm bore provides 2268 N at 0.5 MPa (drive) and 3600 N (holding); if you need more, the 125 mm bore provides 5734 N at 0.5 MPa and 8600 N holding. Operating pressure is capped at 0.7 MPa.
At 450 mm stroke, use a guide to manage side loads and prevent rod binding. The lock is spring-applied and air-released via the G1/8 port. Replacement parts must match the 100 mm bore, 450 mm stroke, PT thread, Basic/LB/FA/TC mounting, and -S magnet option.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 5500 N?
- ✓ Back-rod space for tooling/flag
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Support both rod ends; avoid side load.
- check Use BSED mounting (Basic/LB/FA/TC).
Airtac BSED Clamping Double Acting Cylinder BSED100X450S FAQ
If air is lost or an E-stop trips, the spring-applied collet clamps the rod, providing a 5500 N bidirectional static hold with no live air. It is not a dynamic brake; engage it only after the rod stops, and release it only when both sides are pressure-balanced (allow at least 0.5 s).
The double-rod design provides equal drive force both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum drive of 525 kgf. The static holding force of the lock is 5500 N.
